SUMMARY OF INVENTION Technical Problem

Before purchasing a moving body such as a vehicle, a potential purchaser often visits a retail store for test drive of the moving body to determine the driving feel and usefulness when actually using the moving body. For this reason, it is desirable that the test drive increases the satisfaction level of the potential purchaser who is considering purchasing the moving body.

It is also considered that the satisfaction level of a user of the moving body (owner or the like of the moving body) other than the potential purchaser can be increased by causing the user of the moving body to recognize the use situation of the moving body in which the user has had a good impression.

As described above, simply emailing a standardized thank-you message and product information has a disadvantage of having a low effect of increasing the satisfaction level of the user (test driver, owner, or the like) of the moving body.

An object of the present invention, which has been made in view of such a background, is to provide an information provision device and a moving body capable of more effectively increasing the satisfaction level of the user of the moving body.

Solution to Problem

An information provision device of the present invention is

an information provision device which functions in a moving body, the information provision device comprising:

a user state detection unit which detects a state of a user of the moving body, the user being located in a predetermined area containing the moving body;

an imaging unit which images inside the predetermined area;

an emotion estimation unit which estimates an emotion of the user based on a detection result of the user state detection unit; and

an image transmission unit which causes the imaging unit to image the user when an emotion level of the user estimated by the emotion estimation unit increases, and transmits an image data of the imaged user to a communication terminal of the user when it is estimated or detected that the user has left the predetermined area containing the moving body.

According to the present invention, the user state detection unit detects the state of the user, and the emotion estimation unit estimates the emotion of the user. Then, in response to an increase in the emotion level of the user estimated by the emotion estimation unit, the image transmission unit causes the imaging unit to image the user, and transmits the image data of the imaged user to the communication terminal of the user when it is estimated or detected that the user has left the predetermined area containing the moving body. In this case, the user can view the image which was imaged when the user felt emotionally excited while the user was driving the moving body or operating a door of the moving body through the communication terminal of the user after leaving the moving body. This viewing causes the user to remember the emotionally excited scenes and thus can increase the satisfaction level of the user of the moving body.

Further, the information provision device comprises an information provision unit which provides the user with information encouraging use of a specific function possessed by the moving body, wherein

when the user performs an operation for using the specific function in response to provision of the information and when the emotion level of the user estimated by the emotion estimation unit increases once the user performs the operation, the image transmission unit causes the imaging unit to image the user and transmits the image data of the imaged user to the communication terminal of the user.

This configuration reminds the user of the use situation of the specific function raising the emotion of the user thereby to re-recognize the usefulness of the specific function and to increase the satisfaction level of the user of the moving body.

Further, the image transmission unit transmits the image data of the user together with data indicating the moving body as a sender to the communication terminal of the user.

This configuration allows the user to receive the image data directly transmitted from the moving body, and thus to feel close to the moving body.

Further, the information provision device comprises a moving body image acquisition unit which acquires data of a moving body image showing the moving body, wherein

the image transmission unit transmits the image data of the user together with data of the moving body image to the communication terminal of the user.

This configuration allows the user to intuitively recognize, visually from the image of the moving body, that the image data of the user is directly transmitted from the moving body and thus to feel close to the moving body.

Further, the information provision device comprises a test drive recognition unit which recognizes that the user is test-driving the moving body, wherein

the image transmission unit causes the imaging unit to image the user while the test drive recognition unit recognizes that the user is test-driving the moving body, and when a predetermined time has elapsed since a point of time when a state in which the test drive recognition unit recognizes that the user is test-driving the moving body is switched to a state in which the test drive recognition unit does not recognize that the user is test-driving the moving body, the image transmission unit transmits the image data of the user to the communication terminal of the user.

This configuration reminds the user of the raised emotions occurring to the user by transmitting the image data of the user after a certain interval, and thus can maintain the satisfaction level which the user feels to the moving body.

Then, a moving body of the present invention comprises any one of the above described information provision devices. The moving body comprising the information provision device can exert the same operational effects as the above described information provision devices and thereby can effectively increase the satisfaction level of the user to the moving body.

DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 8.

1. Configuration of a Vehicle Having an Information Provision Device Mounted Thereon

As illustrated in FIG. 1, an information provision device 60 is mounted on a four-wheeled vehicle 1 (which corresponds to a moving body of the present invention and hereinafter referred to as a vehicle 1). Note that the information provision device 60 of the present embodiment is a vehicle-mounted type, but the information provision device of the present invention may be a portable type which can be carried by a user and can be brought into a vehicle for use.

FIG. 1 illustrates a situation where a test driver P1 (which corresponds to the user of the present invention), who is a potential purchaser and is considering purchasing the same type of the vehicle 1, sits on a driver's seat 5R of the vehicle 1, and a salesperson P2 in charge of sales of the vehicle sits on a passenger seat 5L. The salesperson P2 carries a business terminal 9 (such as a tablet and a smartphone) and provides a customer service to the test driver P1 through the business terminal 9.

The vehicle 1 comprises a front camera 11, a front radar 12, a rear camera 13, and a rear radar 14 as the configuration for recognizing the surrounding situation of the vehicle 1, and comprises a navigation device 40 having a global positioning system (GPS) unit 41 and a map database (DB) 42 to be detailed later as the configuration for acquiring route information to the destination.

As the configuration for recognizing the situation of the driver of the vehicle 1, the vehicle 1 comprises a driver's seat camera 20 (which corresponds an imaging unit and a user state detection unit of the present invention) which captures an image of at least a face portion of the driver and a driver's seat microphone 21 (which corresponds a user state detection unit of the present invention) which enters driver's voice. Note that an imaging range by the driver's seat camera 20 and a sound-collecting range by the driver's seat microphone 21 correspond to a predetermined area of the present invention.

As the configuration for detecting an operation performed by a driver on a vehicle operation unit, the vehicle 1 comprises: a steering angle sensor 25 which detects a steering angle of a steering wheel; a torque sensor 26 which detects a steering torque applied to the steering wheel; an accelerator pedal sensor 24 which detects a depression amount of an accelerator pedal; a brake pedal sensor 27 which detects a depression amount of a brake pedal; and a sports mode switch 28 which accepts setting and releasing of a sports mode (a driving mode with improved response, such as control of great increase in driving force relative to accelerator operation).

The vehicle 1 comprises door sensors 30R, 30L, 31R, 31L, and 32 which detect opening and closing of front doors 2R, and 2L, rear doors 3R, and 3L, and back door 4; and seat sensors 33R, 33L, 34R, and 34L which detect the presence or absence of a seated occupant on each of a driver's seat 5R, a passenger seat 5L, and a rear seat 6. Further, the vehicle 1 comprises a speaker 22 (which corresponds a notification unit of the present invention) and a display unit 23 (which corresponds the notification unit of the present invention) for notifying a passenger.

The vehicle 1 comprises a control unit 50 which controls the overall operation of the vehicle 1. The control unit 50 is an electronic circuit unit including a CPU, a memory, various interface circuits, and the like, which are not illustrated. The control unit 50 comprises a communication device 51 and an information provision device 60.

The control unit 50 receives data imaged by the front camera 11, the rear camera 13, and the driver's seat camera 20, and data of an object position detected by the front radar 12 and the rear radar 14. The control unit 50 receives signals detected by the steering angle sensor 25, the torque sensor 26, the accelerator pedal sensor 24, the brake pedal sensor 27, the door sensors 30R, 30L, 31R, 31L, and 32, and the seat sensors 33R, 33L, 34R, and 34L.

Further, the control unit 50 receives an audio signal inputted into the driver's seat microphone 21. In addition, the control unit 50 communicates with the navigation device 40 and communicates with the business terminal 9 and the like via the communication device 51.

In addition, the control unit 50 outputs control signals to control the operation of the speaker 22, the display unit 23, the communication device 51, the navigation device 40, and the like.

2. Configuration of the Information Provision Device

Then, with reference to FIG. 2, the information provision device 60 is formed of the CPU which executes the control programs for the information provision device 60 stored in the memory of the control unit 50. The information provision device 60 comprises a test drive recognition unit 61, a current vehicle information acquisition unit 62, a vehicle information acquisition unit 63, an operation situation detection unit 64, an action detection unit 65, an emotion engine 66 (which corresponds the emotion estimation unit of the present invention), a function-of-interest estimation unit 67, a surrounding situation recognition unit 68, an information provision unit 69, an image transmission unit 70, and a vehicle emotion notification unit 71.

The test drive recognition unit 61 recognizes that the test drive of the vehicle 1 is performed, by the communication with the business terminal 9 or the like. The current vehicle information acquisition unit 62 acquires information on a vehicle (current vehicle) currently owned by the test driver P1, who is test-driving the vehicle 1, by accessing a customer database (DB) 101 of a customer information server 100 via a communication network 110.

The vehicle information acquisition unit 63 acquires information on the ON/OFF of an ignition switch (unillustrated) of the vehicle 1, the operation of a safety device system (unillustrated) (operation of an advanced driver assistance systems (ADAS), an antilock brake system (ABS), an air bag, an emergency call, and the like), vehicle speed, acceleration/deceleration, and the like, through a control area network (CAN) or the like. The operation situation detection unit 64 detects the operation situation of each operation unit of the vehicle 1 operated by the test driver P1 based on the signal detected by each of the sensors 24 to 27, 30R, 30L, 31R, 31L, 32, 33R, 33L, 34R, and 34L. The action detection unit 65 detects the action of the test driver P1 based on the operation situation of each operation unit detected by the operation situation detection unit 64, the situation of the test driver P1, who is driving or located around the vehicle 1, and which is recognized from the images captured by the cameras 11, 13, and 20, and the voice or the like of the test driver P1 inputted into the driver's seat microphone 21.

The emotion engine 66 includes an emotion engine A which estimates the emotion of a driver of the vehicle 1 (herein the test driver P1) and an emotion engine B which generates an emotion of the vehicle 1 by personifying the vehicle 1.

As illustrated in FIG. 3, the emotion engine A quantifies the facial expression of the test driver P1 recognized from the image captured by the driver's seat camera 20; the tone and intonation of voice of the test driver P1 inputted into the driver's seat microphone 21; the operation situation of each operation unit operated by the test driver P1 and detected by the operation situation detection unit 64; and the vehicle information acquired by the vehicle information acquisition unit 63, all of which are plotted on the horizontal axis (axis of calmness) and the vertical axis (axis of steady state) as illustrated in FIG. 3.

Then, based on the quadrants (first quadrant: like, second quadrant: hate, third quadrant: tolerate, and fourth quadrant: calm) to which the plotted points belong and the position of each point in the corresponding quadrant, the degree of each emotion (emotion level) of the test driver P1 (like: the first quadrant, hate: the second quadrant, tolerate: the third quadrant, and calm: the fourth quadrant) is estimated and outputted.

Note that in the present embodiment, the emotion engine 66 uses the facial expression of the test driver P1, the voice of the test driver P1, the operation situation of each operation unit of the vehicle 1, and the vehicle information of the vehicle 1 to estimate the emotion level of the test driver P1, but at least the facial expression and the voice of the test driver P1 may be used to estimate the emotion of the test driver P1. Note also that other factors such as the profile (preference, age, sex, and the like) of the test driver P1 recognized from the customer data of the test driver P1, the biometric information (pulse rate, heart rate, blood pressure, and the like detected by biological sensors) of the test driver P1, the grip condition of the steering wheel gripped by the test driver P1 may be used to estimate the emotion level of the test driver P1.

Further, the emotion engine B quantifies the operation situation of each operation unit of the vehicle 1 detected by the operation situation detection unit 64, the vehicle information of the vehicle 1 acquired by the vehicle information acquisition unit 63, and other information, all of which are plotted on the horizontal axis (axis of calmness) and the vertical axis (axis of steady state) in the same manner as the emotion engine A as illustrated in FIG. 3. Then, based on the quadrants to which the plotted points belong and the position of each point in the corresponding quadrant, the degree (emotion level) of each emotion (like, hate, tolerate, and calm) of the personified vehicle 1 is generated and outputted.

Based on the emotion level of the test driver P1 estimated by the emotion engine A, the function-of-interest estimation unit 67 estimates a specific function assumed to interest the test driver P1 among the functions provided in the vehicle 1.

Based on the images around the vehicle 1 detected by the front camera 11 and the rear camera 13; the objects around the vehicle 1 detected by the front radar 12 and the rear radar 14; traffic information around the vehicle 1 received from the navigation device 40; and other information, the surrounding situation recognition unit 68 recognizes the situation of the road on which the vehicle 1 is travelling.

During the test drive, the vehicle emotion notification unit 71 sends a notification representing the emotion of the vehicle 1 by personifying the vehicle 1 to be detailed later.

3. Information Provision Processing

Then, with reference to the flowchart illustrated in FIG. 4, information provision processing executed by the information provision device 60 for the test driver P1 will be described.

STEP 1 is a process performed by the test drive recognition unit 61. The test drive recognition unit 61 recognizes that the test driver P1 is test-driving the vehicle 1. As illustrated in FIG. 6A, when the test driver P1, who is a potential purchaser of a vehicle, visits a store S of a car dealer, the test driver P1 is captured by a store camera 200 installed at an entrance of the store S, and the captured image data is transmitted to a personal computer 201 located in the store S.

The personal computer 201 analyzes the face image of the test driver P1 and accesses a customer DB 101 held by the customer information server 100 to determine whether the test driver P1 is a new customer (no customer data) or an existing customer (customer data being present). If the test driver P1 is an existing customer, the customer data of the test driver P1 acquired from the customer DB 101 (including the profile, preference, past transaction history, and the like of the test driver P1) is transmitted to the business terminal 9 of the salesperson P2 in charge of the test driver P1 to notify that the test driver P1 has come to the store.

Here, the communication between the business terminal 9 and the personal computer 201 may be performed via the communication network 110 or may be performed by wireless LAN via a wireless router 202 connected to the personal computer 201.

Meanwhile, if the test driver P1 is a new customer, the personal computer 201 selects an appropriate salesperson P2, and transmits, to the business terminal 9 of the selected salesperson P2, data notifying that the test driver P1 has come to the store. In this case, when starting a customer service of the test driver P1 who is a new customer, the salesperson P2 confirms the profile and the like of the test driver P1 to newly generate customer data for the test driver P1.

For the customer service of the test driver P1, the salesperson P2 notifies that the vehicle 1 for test drive is ready and persuades the customer to have a test drive. When the test driver P1 wants to have a test drive, the salesperson P2 transmits, to the information provision device 60 of the vehicle 1, test drive start notification data notifying that the test driver P1 will start test driving and customer data of the test driver P1.

When the test drive start notification data is received, the test drive recognition unit 61 recognizes that the test driver P1 starts the test drive. Then, the process moves to STEP 2. Alternatively, the test drive recognition unit 61 may analyze a conversation voice between the test driver P1 and the salesperson P2 inputted into the driver's seat microphone 21 and from the analysis result, may recognize that test driver P1 performs the test drive.

When an ON (detection state) signal is outputted from the seat sensor 33R of the driver's seat 5R, the test drive recognition unit 61 recognizes that the test driver P1 has got on the vehicle 1, and when the seat sensor 33R indicates an ON state, the test drive recognition unit 61 recognizes that the test driver P1 is test-driving.

Further, from the vehicle information acquired by the vehicle information acquisition unit 63 and the current position of the vehicle 1 acquired by the navigation device 40, the test drive recognition unit 61 recognizes that the vehicle 1 starts test-driving, is test-driving, or ends test-driving.

Based on the change in the current position of the vehicle 1 acquired by the navigation device 40, when it is detected that the vehicle 1 has returned to the store S, and when the output from the seat sensor 33R is switched from the ON signal (detection state) to the OFF state (non-detection state) and the output from the door sensor 30R of the front door 2R on the driver's seat side is switched from the ON signal (detection state) to the OFF state (non-detection state), the test drive recognition unit 61 recognizes that the test drive has ended.

Alternatively, the test drive recognition unit 61 may analyze the conversation voice between the test driver P1 and the salesperson P2 inputted into the driver's seat microphone 21, and from the analysis result (a voice analysis of the salesperson P2 saying, for example, “Thank you very much for your test drive”, the test drive recognition unit 61 may recognize that the test drive of the test driver P1 has ended.

The following STEP 2 is a process performed by the vehicle emotion notification unit 71. While the test drive recognition unit 61 recognizes that the test drive is being performed, the vehicle emotion notification unit 71 sends a notification representing that the vehicle 1 is happy, in STEP 2 as illustrated in FIG. 7A. More specifically, the vehicle emotion notification unit 71 displays, on the display unit 23, an image D1 personifying the state in which the vehicle 1 is happy and at the same time outputs a voice V5 saying, for example, “It's a perfect day for driving!” with a bright tone from the speaker 22.

Alternatively, according to the emotion level “like” of the vehicle 1 outputted from the emotion engine B, the higher the emotion level, the higher the degree of happiness expressed by the image D1 and the voice V5 may be.

The following STEP 3 is a process performed by the emotion engine A. The emotion engine A performs the above described emotion estimation process at a predetermined sampling period and outputs the level of each emotion (like, hate, tolerate, and calm) of the test driver P1 as needed. The following STEP 10 branched from STEP 4 and STEP 5 is a process performed by the image transmission unit 70. In STEP 4, the image transmission unit 70 determines whether or not the emotion level of “like” outputted from the emotion engine A is increased by a predetermined level or more.

Then, if the emotion level of “like” is increased by a predetermined level or more, the process is branched to STEP 10, where the image transmission unit 70 captures an image of the test driver P1 by the driver's seat camera 20 and holds data of the captured image in memory. Then, the process moves to STEP 5. Note that the image may be a still image or a moving image. Meanwhile, if the emotion level of “like” is not increased by a predetermined level or more, the process moves to STEP 5.

STEP 5 and STEP 20 to STEP 22 in FIG. 5 branched from STEP 5 are processes performed by the function-of-interest estimation unit 67. In STEP 5, the function-of-interest estimation unit 67 determines whether or not the action detection unit 65 detects an action of the test driver P1. Then, if an action of the test driver P1 is detected, the process is branched to STEP 20 in FIG. 5. If no action of the test driver P1 is detected, the process moves to STEP 6.

In STEP 20, the function-of-interest estimation unit 67 recognizes the emotion level of the test driver P1 from the output of the emotion engine A. In the following STEP 21, the function-of-interest estimation unit 67 determines whether or not the emotion level of “like” of the test driver P1 is increased by a predetermined level or more. Then, if the emotion level of “like” of the test driver P1 is increased by a predetermined level or more, the process moves to STEP 22. If the emotion level of “like” of the test driver P1 is not increased by a predetermined level or more, the process moves to STEP 6 in FIG. 4.

In STEP 22, the function-of-interest estimation unit 67 extracts a specific function of the vehicle 1 related to the action of the test driver P1 detected in STEP 5. For example, when an action that the test driver P1 opens or closes the back door 4 of the vehicle 1 is detected (when the test driver P1 opens or closes the back door 4, the emotion of “like” of the test driver P1 increases), the function-of-interest estimation unit 67 extracts “rear seat folding function” for enlarging the luggage compartment as the function related to this action.

For example, when an action that the test driver P1 steps on the accelerator pedal to accelerate the vehicle 1 is detected (when the test driver P1 performs an acceleration operation, the emotion of “like” of the test driver P1 is increased), the function-of-interest estimation unit 67 selects “sports mode function” as the function related to this action.

The following STEP 23 to STEP 25, and STEP 30 are processes performed by the information provision unit 69. In STEP 23, the information provision unit 69 determines the presence or absence of the current vehicle of the test driver P1 from the customer data of the test driver P1. Then, if a current vehicle is found, the process moves to STEP 24, where the information provision unit 69 acquires information on a specific function of the current vehicle and a vehicle (competing vehicle) competing with the vehicle 1 of the brand of the current vehicle (generally the manufacturer of the current vehicle).

For example, when the specific function is “sports mode function”, the information provision unit 69 acquires information on “sports mode function” (presence or absence of the sports mode function, elements to be changed by the sports mode function, and the like) of the current vehicle of the test driver P1 and “sports mode function” of a competing vehicle (which corresponds to the competing moving body of the present invention).

Then, in the following STEP 25, the information provision unit 69 notifies the test driver P1 of the information on the specific function of the vehicle 1, the current vehicle, and the competing vehicle by display on the display unit 23 and voice output from the speaker 22. From this notification, the test driver P1 can recognize the specific function of the vehicle 1 in terms of the difference between the current vehicle and the competing vehicle and the advantage thereof.

Meanwhile, if no current vehicle of the test driver P1 is found, the process is branched from STEP 23 to STEP 30, where the information provision unit 69 sends only the information on the specific function of the vehicle 1.

As used herein, the information on the specific function of the vehicle 1 includes information encouraging the use of the specific function. For example, FIG. 6A illustrates a notification sent when “rear seat folding function” is estimated as the specific function that interests the test driver P1, and the information provision unit 69 uses the speaker 22 to output a voice message V1 saying “The rear seats can be easily folded. Please give it a try”. Further, the information provision unit 69 outputs, to the display unit 23, a video explaining the rear seat folding procedure.

Further FIG. 6B illustrates a notification sent when “sports mode function” is estimated as the specific function that interests the test driver P1. More specifically, when the test driver P1 performs an acceleration operation and says that “This acceleration is so nice!”, which voice V2 is inputted into the driver's seat microphone 21. In response to the voice V2, the information provision unit 69 uses the speaker 22 to output a voice V3 saying “Thank you very much! This outstanding acceleration has been achieved by a combination of a high output motor and a low fuel consumption engine.” to appeal the driving performance of the vehicle 1.

Then, on condition that the surrounding situation recognition unit 68 recognizes that the road on which the vehicle 1 is traveling is empty, the information provision unit 69 uses the speaker 22 to output a voice V4 saying that “The road seems to be empty, so why don't you switch to sports mode? Then, you can enjoy driving a lot more. Please try operating the sports mode switch”. Further, the information provision unit 69 outputs, to the display unit 23, a video displaying the position (such as near a shift lever) in which the sports mode switch 28 is placed.

The following STEP 26 and STEP 40 branched from STEP 26 are processes performed by the image transmission unit 70. In STEP 26, the image transmission unit 70 uses the operation situation detection unit 64 to determine whether or not the test driver P1 performed the operation of the specific function.

Then, if the test driver P1 performed the operation of the specific function, the process is branched to STEP 40, and if the test driver P1 did not perform the operation of the specific function, the process moves to STEP 6 in FIG. 4. In STEP 40, the image transmission unit 70 uses the driver's seat camera 20 to image the test driver P1 and hold the imaged data in memory, and then the process moves to STEP 6 in FIG. 4. Note that when the test driver P1 performed the operation of the specific function, in STEP 40, the image transmission unit 70 uses the driver's seat camera 20 to image the test driver P1 and hold the imaged data in memory, but when the test driver P1 performed the operation of the specific function and the emotion level of the test driver P1 is increased by a predetermined level or more, in STEP 40, the image transmission unit 70 may use the driver's seat camera 20 to image the test driver P1 and hold the imaged data in memory.

STEP 6 and STEP 7 in FIG. 4 are processes performed by the vehicle emotion notification unit 71. In STEP 6, the vehicle emotion notification unit 71 determines whether or not the test drive recognition unit 61 recognizes that the test driver P1 ends the test drive of the vehicle 1. Then, if the end of the test drive is recognized, the process moves to STEP 7, and if the end of the test drive is not recognized, the process returns to STEP 2, where the process following STEP 2 is executed again.

In STEP 7, the vehicle emotion notification unit 71 notifies that the vehicle 1 feels sad as illustrated in FIG. 7B. More specifically, the vehicle emotion notification unit 71 displays, on the display unit 23, an image D2 personifying the state in which the vehicle 1 feels sad, and at the same time outputs a voice V6 saying that “I'm very sorry to see you go. Hope to see you again.” from the speaker 22 with a heavy tone.

The following STEP 8 is a process performed by the image transmission unit 70. The image transmission unit 70 extracts the address of the test driver P1 from the customer data of the test driver P1. With reference to FIG. 8, the image transmission unit 70 calculates the distance from the store S (test drive ending location) to a home H of the test driver P1 to predict the time (expected time to return home) for the test driver P1 to return to the home H. Note that the time elapsed from the time when the test drive ended to the expected time to return home corresponds the predetermined time of the present invention.

Then, when the time reaches the expected time to return home, the image transmission unit 70 transmits an email 400 expressing appreciation for the test drive to a communication terminal 300 (a smartphone, a tablet, a mobile phone, and the like) of the test driver P1 via a mail server 120.

The email 400 contains an image 401 of the test driver P1 captured in STEP 10 of FIG. 4 or in STEP 40 of FIG. 5; a thank-you document 402; and an image 403 of the vehicle 1 or a vehicle of the same type and the same color as the vehicle 1.

The image 403 corresponds the moving body image of the present invention and the configuration where the image transmission unit 70 acquires data of the image 403 from the customer information server 100 or the like corresponds to the moving body image acquisition unit of the present invention.

Since the image 401 of the test driver P1 is an image captured when the emotion level of “like” of the test driver P1 is increased by a predetermined level or more, the image 401 is basically a smile image. If a plurality of images are captured, smile detection is performed on each image, and an image with the highest smile level may be selected from among the detected smile images and may be used as the image 401 of the test driver P1 to be attached to the email 400.

Further, the addresser of the email 400 is a vehicle type name (illustrated by “HT-SPORT” in FIG. 8) of the vehicle 1, which can enhance the impression of the test driver P1 to this type of vehicle by including the image 403 of the vehicle 1 or a vehicle of the same type and the same color as the vehicle 1.

4. Other Embodiments

The above embodiment has been described using an example where the test driver P1 performs test drive of the vehicle 1. When the user uses his or her own vehicle, the user can be made to recognize the usefulness of the current vehicle by providing information on the specific function assumed to interest the user in the same manner as described above.

In the above embodiment, a still image (image 401) of the test driver P1 is attached to the email 400, but a moving image of the user P1 may be attached thereto. Further, when the image of the test driver P1 is captured, data of the voice emitted by the test driver P1 may be recorded and attached to the email together with the image. Furthermore, when the test rider P1 has contracted the purchase of the vehicle, the contract date, the expected delivery date, and the like may be included in the email and the image information.

In the above embodiment, in STEP 8 of FIG. 4, the image transmission unit 70 sends an email to the test driver P1 by assuming the time for the test driver P1 to return home, but the email may be sent to the test driver P1 when it is estimated or detected that the user P1 has left the predetermined area including the vehicle 1. In this case, the image transmission unit 70 may recognize that the user P1 has left the predetermined area including the vehicle 1, for example, (1) when a predetermined time has elapsed from when it was recognized from the images and the like captured by the cameras 11, 13, and 20 that the user P1 left the vehicle 1, or (2) when a predetermined time has elapsed from when the user P1 ended the test drive of the vehicle 1 or the user performed the operation such as folding the seat.

The above embodiment comprises the action detection unit 65 and the emotion engine 66 and the function-of-interest estimation unit 67 estimates the specific function that interests the user based on the action of the user detected by the action detection unit 65 and the emotion of the user estimated by the emotion engine A when the action is detected. Alternatively, another embodiment may comprise only the action detection unit 65 and the function-of-interest estimation unit 67 may estimate the specific function based on the action of the user detected by the action detection unit 65. Alternatively, another embodiment may comprise only the emotion engine 66 and the function-of-interest estimation unit 67 may estimate the specific function that interests the user based on the emotion of the user P1 detected by the emotion engine 66.

The above embodiment has described the four-wheeled vehicle 1 as the moving body of the present invention, but the present invention may be applied to various types of moving bodies including other types of vehicles such as two-wheeled vehicles, ships, airplanes, and the like.
